CHARLES I-I. JOCKMUS, OF ANSONIA, CONNECTICUT.

SPLASH-FEED OIL-CUP.

Specification of Letters Patent.

Patented Aug. 19, 1919.

Application led March 1, 1919. Serial No. 279,958.

To allwhom 1f/may concern:

Be it known that I, CHARLES H. JooKMUs, a citizen of the United States, residing at Ansonia, county of New Haven, State of Connecticut, have invented an Improvement in Splash-Feed Cil-Cups, of which the following is a specification.

This invention relates to\oil cups of the splash feed type and has for its object to provide a construction that will avoid the irre ularity and uncertainty of feeding that has eretofore existed in all splash feed oil cups, so far as I am aware, and insure regularity and certainty of feeding so long as au appreciable amount of oil remains in the reservoir.

With this and other objects in view I have devised the novel improvement in splash feed oil cups which I will now describe referring to the accompanying drawing formino' a part of this specification and using reference characters to indicate the several parts.

Figure 1 is an elevation of my novel oil cup;

Fig. 2 a longitudinal section thereof, partly in elevation;

Fig. 3 a perspective view of the stem detached, and

Fig. 4 is a longitudinal vsection partly in elevation illustrating a variant form of the invention.

10 denotes the body, which is provided with an oil reservoir 11, and with an externally threaded hub 12 by which it is attached in place for use. 13 denotes the stem, the lower end of which has threaded engagement with the hub, and which is provided with a head 14 at its upper end, and a longitudinal bore 15 which is in alinement with a similar bore 16 in the hub. 17 denotes a cap which is adapted to slide closely over the body and is provided with a central hole 18 through which the stem passes freely but which is of less diameter than the head. A spring 19 bearing against the inner side of the cup and the bottom of the reservoir acts to press the cap tightly against the head and thus keep the reservoir closed. In order to lill thel reservoir it is simply necessary to press the cap downward against the power of the spring which leaves the reservoir uncovered and permits convenient filling.

This typeof oil cups is adapted for use Copies of this patent may be obtained for ve cents each, by/ addressing the upon moving parts, as upon engine crank rods, the movement of4 the part carrying the cup causing the oil in the reservoir to splash up on the stem. A plurality of holes 20 leading from the exterior of the stem to the bore thereof receives some of the oil that is splashed up on the stem and conducts it into the bore, the oil passing down the bores in the stem and the hub to the place where it is required. In order to facilitate the passage of oil from the exterior of the stem into the bore, holes 20 are causedto incline downward from the exterior of the stem to the bore. This, however, does not at all times insure a regular and constant supply of oil through the bore. I, there fore, provide the exterior of the stem with a circular trough 21 from which the holes lead downward at an angle into the bore. This trough catches and retains oil that is splashed up on the stem thereby insuring a constant and uniform supply of oil through the holes in the stem to the bore and thence to the part or parts to be lubricated.

The special manner in which the trough is formed is not an essential feature of the invention. In Figs. 2 and 3 I have shown a form in which the trough is formed by removing metal entirely around the stem, the trough being in fact a circular groove in the stem, both walls of which are downwardly extending inclines which meet at the bottom of the groove.

In the form illustrated inl Fig. 4, the stem is provided with a collar around the outside thereof in which the trough is formed.

Having thus described my invention, I claim:

An oil cup comprising a body having a reservoir and an attaching hub, a stem secured in the hub and having a head, the stem and hub being provided with a bore and the stem being provided intermediate the hub and the head with a circular trough and with inclined openings leading from the trough into the bore, a cap adapted to slide 'closely over the body and having a hole through which the stem passes freely but which is of less diameter than the head, and a spring acting to normally hold the cap against the head and retain the reservoir closed.

In testimony whereof I aix my signature.
